+%description
+IOzone is a filesystem benchmark tool. The benchmark generates and 
+measures a variety of file operations. Iozone has been ported to 
+many machines and runs under many operating systems.
+ 
+Iozone is useful for performing a broad filesystem analysis of a vendors
+computer platform. The benchmark tests file I/O performance for the following
+operations: Read, write, re-read, re-write, read backwards, read strided,
+fread, fwrite, random read, pread ,mmap, aio_read, aio_write.
